Hardened Steel Extruder Gear Upgrade Kit for Bambu Lab X1/X1C/P1P/P1S

### Full Metal Upgrade for Bambu Lab Extruder
Replaces the original gears with high-grade brass drive gear and hardened steel idler gear, solving the common issue of gear wear and filament slipping in long-term printing.
### Wear-Resistant and Long-Lasting Performance
Brass gears feature excellent self-lubricating properties, while hardened steel idler gear offers superior wear resistance, ideal for printing abrasive materials like carbon fiber-filled filaments.
### Precision CNC Machined for Accurate Feeding
Tight tolerance machining ensures smooth gear meshing, eliminates backlash, and provides precise filament control, leading to more consistent extrusion and higher print quality.
### Low-Inertia Lightweight Design
Five-spoke hollow structure reduces gear inertia, allowing faster response to retraction and feed commands, which is crucial for high-speed printing.
### Complete Kit for Direct Replacement
Comes with all necessary components (gear set, aluminum idler arm, bearings, and grease), perfect direct fit for Bambu Lab X1/X1C/P1P/P1S extruders, no modification needed.
